Problem: FT8, KX3, SignaLink USB

[N3AO]

I am setting up my KX3 for FT8 using a SignaLink USB interface. My computer
runs Windows 10.

For PTT, I have checked the CAT option.

When I do the test for CAT and PTT, the test works correctly. CAT tests
okay, and PTT toggles on and off.

However, in a QSO, the PTT does not work correctly. It puts the rig into
transmit but at the end of my transmission, the SignaLink drops into
Receive but the KX3 stays in Transmit. Stuck in Transmit. Only turning off
the KX3 gets it out of transmit.

My setup works properly for PSK31 using Ham Radio Deluxe software, so I
believe the FT8 problem lies somehow with how I have set up WSJT-X. I've
been told that the KX3 can get its brains scrambled in combination with a
SignaLink by getting conflicting PTT commands.

If someone is successfully using WSJT-X with a KX3 and a SignaLink USB
interface, I would appreciate your suggestions and advice. On the reflector
or by off-reflector e-mail is fine.

Thanks very much and 73,
Carter N3AO

Carter,

Do you also have VOX active?  With both PTT and VOX on, that will happen.
